Why did the Komagata maru happen?

The Komagata Maru incident occurred in 1914 when a Japanese ship carrying Indian immigrants, primarily Sikhs, was denied entry into Canada due to restrictive Immigration laws aimed at curbing non-European immigration. The passengers, who sought better opportunities and escape from British colonial rule, were stranded in Vancouver for two months before being forced to return to India. Upon their return, they faced hostility and repression from British authorities, highlighting the racial discrimination and exclusionary policies of the time. This incident became a significant moment in the history of Indian diaspora and anti-colonial movements.
